Over the past few years, I’ve travelled extensively across Southeast Asia, experiencing firsthand the environmental challenges this vibrant region faces. My previous articles have delved into the severe air pollution crises in Thailand, the Philippines, India, and Vietnam, each offering unique challenges and solutions. As part of this ongoing series exploring air pollution in countries I’ve visited, I want to turn my focus to Indonesia – a nation with a complex and deeply rooted struggle against air pollution.
A couple of years ago, I had the opportunity to visit Jakarta, Denpasar, and Bali during June and August. Although my stay was brief – just a couple of weeks – the severity of the air pollution, particularly in Jakarta, left a lasting impression on me. The dense smog, the smell of burning, and the constant haze obscuring the skyline were daily reminders of Indonesia’s environmental crisis. These experiences reminded me of my years living in South Korea, where I extensively wrote about air pollution challenges. However, in Indonesia, the issue felt even more immediate and pervasive.
As of writing this, Jakarta sits as the second most polluted city in the world.
Today, Jakarta has gained global notoriety as one of the most polluted cities in the world, currently ranked as the second most polluted city according to IQ Air’s latest rankings. But the problem extends far beyond the capital. Air pollution is a prevalent and persistent issue across the entire country, from the industrial centres of Java to the agricultural regions of Sumatra and Kalimantan. The infamous haze from forest fires, driven by slash-and-burn practices, not only chokes the air in Indonesia but also spreads across borders, affecting the entire Southeast Asian region.
In this article, I aim to provide a comprehensive overview of the factors contributing to Indonesia’s air pollution, the health impacts on its population, and the measures being taken to combat the crisis. Whether you’re a resident, a traveller, or simply someone concerned about environmental issues, I hope this guide will equip you with the knowledge and tools to understand and navigate Indonesia’s air quality challenges better.
I also want to note that, yes, I spent only a short time in Indonesia, so this article is written largely based on research I’ve found online. If you are interested in reading more, please refer to the sources I have provided. These will delve into far more depth about each individual topic, and I highly recommend reading them if you are interested in the topic and want to learn more. With that said, let’s dive in!

Air pollution is a severe and pervasive issue in Indonesia, affecting millions across its vast archipelago. The problem has escalated to alarming levels recently, with Tangerang, Jakarta, and Bandung frequently ranking among the most polluted cities globally. As of 2023, South Tangerang is the most polluted city in Southeast Asia, according to IQAir’s report, with average daily PM2.5 concentrations often exceeding 150 µg/m³. This level is more than ten times the World Health Organization (WHO) guideline for safe air, which sets the annual mean exposure limit at 15 µg/m³ for PM2.5.
Indonesia’s air pollution crisis is not confined to its capital. Across the country, other cities like Surabaya and Medan also report hazardous air quality levels, particularly during the dry season when forest fires are most prevalent. The Air Quality Life Index (AQLI) by the Energy Policy Institute at the University of Chicago (EPIC) estimates that air pollution in Indonesia reduces life expectancy by an average of 2.3 years. In some regions, such as Central Kalimantan, life expectancy is reduced by more than five years due to chronic exposure to fine particulate matter (PM2.5).

A significant contributor to this crisis is the annual occurrence of forest and peatland fires, especially in Sumatra and Kalimantan. These fires often start to clear land for agriculture, producing massive amounts of haze that blanket large areas, including neighbouring countries like Malaysia and Singapore. In 2019, the Indonesian National Disaster Management Agency (BNPB) reported that the fires affected over 1.6 million hectares of land, releasing an estimated 708 million tons of CO2 – more than the annual emissions of the entire United Kingdom.
The health impact of these fires is staggering. The World Bank estimates that the 2019 haze crisis led to over 900,000 cases of acute respiratory infections in Indonesia alone. Furthermore, a study by Harvard and Columbia Universities found that long-term exposure to the particulate matter from these fires could result in an additional 36,000 premature deaths annually across Southeast Asia.
Transportation is another major source of air pollution in Indonesia, particularly in urban areas like Jakarta, where vehicle emissions account for nearly 80% of the city’s air pollution. The sheer volume of traffic, coupled with the ageing and poorly maintained vehicle fleet, contributes significantly to the high levels of nitrogen dioxide (NO2) and particulate matter in the air. The Indonesian Ministry of Environment and Forestry (KLHK) reports that the transportation sector is the most significant contributor to urban air pollution, with emissions from vehicles being a leading cause of respiratory and cardiovascular diseases.
Air pollution disproportionately affects Indonesia’s most vulnerable populations, including children, the elderly, and those with preexisting health conditions. Many children in Indonesia are exposed to high levels of air pollution, which can lead to severe health issues such as asthma, pneumonia, and impaired cognitive development. The economic impact is also significant, with the World Bank estimating that air pollution costs Indonesia approximately 2% of its GDP annually due to healthcare expenses and lost labour productivity.
In summary, air pollution in Indonesia is a critical public health and environmental issue that demands urgent attention. The severity of the problem is evident in the country’s poor air quality rankings, the widespread occurrence of pollution-related illnesses, and the extensive damage caused by annual forest fires. Addressing this crisis requires comprehensive policy interventions, public awareness campaigns, and international cooperation to mitigate the impacts and protect the health of Indonesia’s population.
What Causes Air Pollution in Indonesia?
Air pollution in Indonesia is a multifaceted problem, with several key factors contributing to the poor air quality experienced across the country. The causes vary significantly depending on the region, reflecting Indonesia’s diverse geography, economy, and population distribution. Understanding these sources is crucial to addressing the air pollution crisis effectively.
Forest Fires and Haze
One of Indonesia’s most significant contributors to air pollution is the widespread practice of slash-and-burn agriculture, particularly in the provinces of Sumatra and Kalimantan. These fires are often set intentionally to clear land for palm oil plantations and other agricultural purposes. The resulting haze can blanket large parts of Indonesia for weeks or even months, leading to hazardous air quality levels locally and in neighbouring countries like Malaysia and Singapore.
The annual haze crisis typically peaks during the dry season, from June to October, when the lack of rainfall exacerbates the spread of fires. In 2019 alone, over 1.6 million hectares of land were burned, releasing massive amounts of particulate matter (PM2.5) and other pollutants into the atmosphere. The smoke from these fires contains a toxic mix of gases and fine particles that pose severe health risks, contributing to respiratory and cardiovascular diseases and increasing the risk of premature death.
Urbanization and Transportation
Indonesia’s rapid urbanization, particularly in cities like Jakarta, Surabaya, and Bandung, has led to a sharp increase in vehicular emissions, which are a major source of air pollution. The transportation sector, dominated by a large and ageing fleet of vehicles, contributes significantly to the levels of nitrogen dioxide (NO2), carbon monoxide (CO), and particulate matter in the air. Traffic congestion is a chronic problem in these cities, further aggravating the emission levels.
Jakarta, in particular, suffers from severe air pollution due to its dense population and heavy reliance on motor vehicles. The city’s air quality is frequently categorized as “unhealthy” or worse, with PM2.5 levels often exceeding safe limits by a wide margin. The combination of vehicle emissions, industrial activities, and construction dust creates a persistent smog that hangs over the city, reducing visibility and posing a constant health threat to its residents.
Industrial Activities
Indonesia’s industrial sector is another major contributor to air pollution, especially in regions with a high concentration of factories and manufacturing plants. Industries such as cement production, petrochemicals, mining, and pulp and paper manufacturing release large quantities of sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate matter into the atmosphere.
The rapid expansion of industrial activities, particularly in West Java and East Kalimantan, has led to localized pollution hotspots where air quality is often hazardous. These industrial emissions degrade air quality and contribute to acid rain, which can harm ecosystems, damage buildings, and negatively impact agricultural productivity.
Agricultural Practices
Beyond the slash-and-burn methods used in forest clearance, other agricultural practices also contribute to air pollution in Indonesia. The use of traditional biomass for cooking and heating in rural areas leads to the emission of black carbon and other harmful pollutants. This issue is particularly pronounced in less developed regions, where access to cleaner energy sources is limited.
Additionally, burning crop residues after harvest is a common practice in some parts of Indonesia. While effective for clearing fields, this method releases large amounts of smoke and particulate matter into the air, further exacerbating air pollution problems in rural areas.
Waste Management Issues
Inadequate waste management practices also play a role in Indonesia’s air pollution. Open burning of waste, including plastic, is a common sight in many parts of the country, especially in areas with limited waste collection services. This practice releases a variety of harmful pollutants, including dioxins, furans, and heavy metals, into the air, contributing to both local and regional air quality degradation.
Natural Factors
While human activities are the primary drivers of air pollution in Indonesia, natural factors such as volcanic eruptions also contribute to the problem. Indonesia, located on the Pacific Ring of Fire, is home to numerous active volcanoes. Volcanic eruptions can release large amounts of ash, sulfur dioxide, and other gases into the atmosphere, temporarily worsening air quality in surrounding areas.
Transboundary Pollution
Due to Indonesia’s geographical location and the transboundary nature of air pollution, the country is both a source and a recipient of pollutants from neighbouring nations. For example, the haze from forest fires often drifts across borders, impacting air quality in Malaysia, Singapore, and even Thailand. Conversely, pollutants from these countries can also affect air quality in Indonesia, making it a regional issue that requires cooperative efforts to address effectively.
The causes of air pollution in Indonesia are varied and complex, reflecting the country’s diverse landscape and economic activities. From the devastating impact of forest fires to the emissions from urban transportation and industrial activities, each source contributes to the overall air quality crisis that affects millions of Indonesians daily. Addressing these causes requires a multifaceted approach that includes stricter enforcement of environmental regulations, investment in cleaner technologies, and regional cooperation to tackle transboundary pollution.
Health Effects of Air Pollution in Indonesia
Air pollution is not just an environmental issue; it has serious implications for public health, particularly in a country like Indonesia, where pollution levels are frequently hazardous. As mentioned earlier in this article, air pollution is responsible for over 36,000 premature deaths annually in Indonesia, and its impact on public health cannot be overstated. It’s also worth noting that the actual number of deaths due to air pollution is likely far higher, but since so much air pollution impacts the body in so many ways, it’s impossible to link every related death to air pollution.
Short-Term Health Effects
The immediate effects of exposure to high levels of air pollution are often seen in the form of acute respiratory conditions. During periods of severe haze, such as those caused by forest fires, hospitals and clinics report a sharp increase in cases of asthma, bronchitis, and other respiratory ailments. The World Bank noted that the 2019 haze crisis led to over 900,000 cases of acute respiratory infections in Indonesia, highlighting air pollution’s direct and immediate impact on health.
Children, the elderly, and individuals with preexisting health conditions are particularly vulnerable to these short-term effects. For instance, during the dry season, when air quality in cities like Jakarta deteriorates significantly, there is a noticeable rise in emergency room visits for respiratory issues. These conditions can be exacerbated by the frequent presence of fine particulate matter (PM2.5), which can penetrate deep into the lungs and enter the bloodstream, leading to immediate health problems.
Long-Term Health Effects
The long-term health effects of air pollution are even more concerning. Prolonged exposure to polluted air, particularly in urban areas where PM2.5 levels regularly exceed safe limits, can lead to chronic respiratory diseases, cardiovascular conditions, and even certain types of cancer. As highlighted in the introduction, the Air Quality Life Index (AQLI) estimates that air pollution reduces life expectancy in Indonesia by over two years, with some regions experiencing even greater reductions.
Studies have also linked long-term exposure to air pollution with developmental issues in children, including impaired lung function and cognitive development. The presence of heavy metals and other toxic substances in the air can have lasting effects on the nervous system, particularly in young children who are still developing.
Mental Health Impacts
Emerging research also suggests that air pollution can have adverse effects on mental health. Exposure to high levels of air pollution has been associated with increased risks of depression, anxiety, and other mental health disorders. While this is a relatively new area of study, the evidence is growing that poor air quality can affect not only physical health but also mental well-being.
Indirect Health Impacts
Beyond the direct physical and mental health impacts, air pollution in Indonesia also has significant indirect effects. The economic burden of pollution-related health conditions – such as lost productivity due to illness and the cost of medical treatment – is substantial. Families often face financial strain due to the need for ongoing medical care, particularly in regions where access to healthcare is limited.
While this article focuses on the context of air pollution in Indonesia, it’s important to acknowledge the broader health implications of polluted air. The short-term and long-term health effects are severe, contributing to both acute medical emergencies and chronic conditions that can last a lifetime. For a more detailed exploration of the health impacts of air pollution, I encourage you to read my dedicated article on this topic, which delves deeper into the global and regional effects of air pollution on public health.
Seasonality of Air Pollution in Indonesia

As with many countries, air pollution in Indonesia is highly seasonal, with distinct periods of the year when pollution levels spike due to natural and human-induced factors. Understanding these seasonal patterns is crucial for residents and visitors to effectively plan their activities and take precautions to protect their health.
The Dry Season and Forest Fires
The dry season, typically from June to October, is the most significant seasonal driver of air pollution in Indonesia. During this period, the country experiences reduced rainfall, creating the perfect conditions for forest and peatland fires, particularly in Sumatra and Kalimantan. These fires, often started to clear land for agriculture, generate massive amounts of smoke and haze that blanket large regions, leading to hazardous air quality levels.
The haze from these fires can spread across hundreds of kilometres, affecting not only rural areas but also major cities like Jakarta and Palembang. In severe cases, the haze can even cross national borders, impacting air quality in neighbouring countries such as Malaysia and Singapore. The severity of the haze season varies from year to year, depending on the intensity of the fires and the prevailing weather conditions. For instance, during El Niño years, the dry season tends to be more prolonged and intense, exacerbating the frequency and scale of the fires.
The health implications during the dry season are particularly severe. As the haze intensifies, respiratory issues surge, with vulnerable groups like children, the elderly, and those with preexisting health conditions being the most affected. Schools often have to close, flights are cancelled (I was impacted by this when I visited), and daily life is disrupted as visibility drops and air quality reaches hazardous levels.
Urban Air Pollution Patterns
In Indonesia’s urban centres, such as Jakarta, Surabaya, and Bandung, air pollution levels also exhibit seasonal variations, though different factors influence them than those affecting rural areas. In cities, the combination of vehicular emissions, industrial activity, and construction dust contributes to consistently high levels of air pollution year-round. However, during the dry season, the lack of rain can cause pollutants to accumulate in the atmosphere, leading to worsened air quality.

Conversely, the rainy season, which runs from November to March, generally relieves urban areas as the rain helps wash pollutants out of the air. However, this does not mean that air pollution disappears entirely; it may shift in nature. For example, the rainy season can increase indoor air pollution as people spend more time indoors, often using biomass for cooking and heating, which generates harmful smoke.
Urban areas also face pollution spikes during periods of high traffic congestion, which can be exacerbated by seasonal festivals or holidays when more vehicles are on the road. For instance, during the holiday of Idul Fitri, millions of Indonesians travel across the country, leading to massive traffic jams and a corresponding spike in air pollution levels in major cities.
Impact of Agricultural Practices
Seasonal agricultural practices also contribute to the fluctuation of air pollution levels in Indonesia. Beyond forest fires, crop residue burning after harvest is a common practice, particularly in Java and Sumatra. These agricultural burns typically occur at the end of the dry season and contribute to localized spikes in air pollution. While these burns are smaller in scale than forest fires, they still release significant amounts of particulate matter and other pollutants into the air.
The timing of these agricultural burns often coincides with the beginning of the rainy season, leading to a dangerous combination of pollutants in the air just as people begin to spend more time indoors. The smoke from these burns can linger in the air for days, affecting rural communities and nearby urban areas.
Volcanic Activity
Unlike the other countries I’ve written these articles about, volcanic activity can also significantly impact Indonesia’s air quality. While not as frequent as other sources, volcanic activity can significantly impact air quality when it occurs. For instance, the eruption of Mount Sinabung in North Sumatra or Mount Merapi in Central Java can release large quantities of ash and sulfur dioxide (SO2) into the atmosphere, leading to temporary but severe air pollution in surrounding areas.
Volcanic eruptions can also exacerbate existing pollution problems. For example, ash from an eruption can combine with urban smog to create a dense haze that is difficult to disperse, leading to prolonged periods of poor air quality. Depending on the scale of the eruption and the prevailing weather conditions, the effects of volcanic eruptions on air quality can last for weeks or even months.
Geography and Regional Variations in Air Pollution
Indonesia’s vast and diverse geography plays a crucial role in shaping the patterns and severity of air pollution across the country. From densely populated urban centres to remote rural areas, the influence of geography on air quality is evident. Understanding these geographical variations (alongside the seasonal variations) is vital for planning ahead.
Urban vs. Rural Areas
Air pollution in Indonesia exhibits stark contrasts between urban and rural areas. In major urban centres such as Jakarta, Surabaya, and Bandung, air pollution is primarily driven by vehicular emissions, industrial activities, and construction dust. The high population density and concentration of economic activities in these cities lead to consistently poor air quality, with particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) levels frequently exceeding safe limits.
Jakarta, the capital city, is a prime example of how urbanization exacerbates air pollution. The city’s sprawling metropolitan area, combined with chronic traffic congestion and a reliance on fossil fuels, results in persistent smog and unhealthy air quality. Jakarta’s flat, low-lying geography also contributes to the problem, as pollutants tend to become trapped in the atmosphere, especially during periods of low wind and high humidity. This is similar to why other areas such as Hanoi and New Delhi also experience severe pollution due to geography.
In contrast, rural areas face different air pollution challenges, particularly in regions like Sumatra and Kalimantan. While these areas are less affected by vehicular emissions, they are heavily impacted by agricultural practices, such as slash-and-burn farming and forest fires. Burning peatlands in these regions releases large amounts of carbon dioxide (CO2), methane (CH4), and other pollutants into the air, creating hazardous conditions that can persist for months.
Coastal vs. Inland Regions
Indonesia’s coastal regions experience different air pollution dynamics compared to inland areas. Coastal cities like Jakarta, Surabaya, and Denpasar are often affected by maritime activities, including shipping and port operations, which contribute to air pollution through emissions from ships and industrial facilities located near ports. The coastal breeze can sometimes help disperse pollutants but can also carry pollutants from ships and industrial zones further inland, impacting a broader area.
Inland regions, especially those surrounded by mountains or highlands, can experience different pollution patterns due to geographical barriers that trap air masses and pollutants. For example, Bandung, situated in a basin surrounded by mountains, often experiences temperature inversions that trap pollutants close to the ground, leading to poor air quality, particularly during the dry season.
Industrial vs. Agricultural Regions
The geographical distribution of industrial and agricultural activities across Indonesia also significantly affects regional air pollution levels. Industrial regions, such as those in West Java and East Kalimantan, are hotspots for pollution due to the concentration of factories and processing plants. These areas emit large quantities of SO2, NOx, volatile organic compounds (VOCs), and particulate matter, contributing to local and regional air quality issues.
Agricultural regions, particularly in Sumatra and Kalimantan, are heavily impacted by seasonal fires used to clear land for crops, particularly palm oil and pulpwood plantations. The geography of these regions, with extensive peatlands that are highly flammable, exacerbates the air pollution problem. When these peatlands burn, they release vast amounts of smoke and haze, affecting the immediate area and neighbouring regions and countries.
The Role of Volcanoes
Indonesia’s position on the Pacific Ring of Fire means that volcanic activity is another geographical factor influencing air pollution. Volcanic eruptions, while less frequent than other pollution sources, can significantly impact air quality. When a volcano erupts, it can release large amounts of ash, SO2, and other gases into the atmosphere, leading to poor air quality over wide areas.
For instance, the eruption of Mount Merapi in Central Java or Mount Sinabung in North Sumatra can create ash plumes that travel hundreds of kilometres, affecting air quality in multiple provinces. These eruptions can lead to short-term spikes in air pollution, with ashfall causing respiratory issues and reducing visibility. The impact of volcanic activity on air quality is often compounded by the existing pollution from human activities, leading to severe and prolonged episodes of poor air quality.
Transboundary Pollution
Indonesia’s geographical location also makes it a source and recipient of transboundary air pollution. During the dry season, the smoke from forest fires in Sumatra and Kalimantan often drifts across borders, affecting air quality in neighbouring countries like Malaysia and Singapore. This transboundary pollution is heavily influenced by prevailing wind patterns, which can carry haze far beyond Indonesia’s borders, exacerbating regional air quality issues.
Conversely, Indonesia can also be affected by pollution from other countries, particularly during periods when winds carry pollutants from industrial activities or agricultural burning in neighbouring nations. The interaction between local and transboundary pollution sources adds another layer of complexity to the air quality challenges faced by different regions of Indonesia.
What Is Being Done to Address Air Pollution?
Indonesia Air Quality Policies as of 2015.
Addressing the complex and multifaceted issue of air pollution in Indonesia requires a concerted effort from the government, private sector, non-governmental organizations (NGOs), and the international community. Over the years, various initiatives and policies have been introduced to mitigate the effects of air pollution, though the challenges remain significant.
Government Initiatives and Policies
The Indonesian government has recognized air pollution as a critical issue and has introduced several initiatives to reduce emissions from vehicles, industrial facilities, and agricultural practices. Efforts include tightening vehicle emissions standards, promoting the adoption of cleaner technologies like electric vehicles, and enhancing the monitoring and regulation of industrial emissions. However, enforcement remains a challenge due to issues like non-compliance and corruption.
To combat the recurring haze crisis caused by forest fires, the government has focused on restoring degraded peatlands and promoting sustainable land management practices. While these efforts have made some progress, the economic incentives driving illegal land clearing continue to pose significant obstacles.
Regional and International Cooperation
Given the transboundary nature of air pollution, Indonesia has engaged in regional cooperation through the ASEAN Agreement on Transboundary Haze Pollution. This collaboration aims to prevent and mitigate haze pollution by sharing information and implementing early warning systems. Additionally, Indonesia has received international support for air quality improvement projects, including funding for cleaner energy and environmental monitoring.
Bilateral agreements with neighbouring countries like Malaysia and Singapore have also been established to address the cross-border impacts of haze, focusing on fire prevention and sustainable land management.
Technological Innovations
Technological advancements play a significant role in Indonesia’s efforts to combat air pollution. The government, in partnership with private sector players, has deployed air quality monitoring systems across the country, providing real-time data to the public. In urban areas, smart city initiatives and sustainable transportation systems, like the TransJakarta bus rapid transit, aim to reduce emissions from traffic.
In the agricultural sector, there is a push towards more sustainable farming practices that reduce the need for burning. These practices not only help to lower pollution levels but also contribute to better land management.
NGOs and Community Efforts
Non-governmental organizations (NGOs) and community groups have been instrumental in raising awareness about the impacts of air pollution and advocating for stronger environmental regulations. Organizations like Greenpeace Southeast Asia and WALHI have led campaigns to promote transparency, hold polluters accountable, and encourage behavioural changes that contribute to cleaner air.
Grassroots movements have also gained traction, with local communities initiating reforestation projects, peatland restoration efforts, and waste reduction campaigns. These community-driven initiatives play a vital role in complementing government efforts and addressing air pollution at the local level.
Challenges and Future Directions
Despite these efforts, significant challenges remain in addressing air pollution in Indonesia. Corruption, limited resources, and conflicting economic interests often hinder the enforcement of environmental regulations. The haze crisis, driven by the lucrative palm oil and pulpwood industries, continues to be a major issue.
While technological innovations and regional cooperation offer hope, their impact is constrained by the scale of the problem and the need for widespread adoption. Addressing air pollution in Indonesia will require sustained commitment from all stakeholders, including ongoing investment in cleaner technologies, stronger enforcement of environmental laws, and increased public participation in pollution control efforts.
Understanding and Monitoring Air Quality in Indonesia
U.S. EPA AQI.
Air pollution is a critical issue in Indonesia, and understanding how to monitor and interpret air quality data is essential for residents and visitors. The Air Quality Index (AQI) is the most commonly used tool for this purpose, providing a clear and standardized way to assess air quality levels and their potential impact on health.
Understanding the Air Quality Index (AQI)
Indonesia primarily uses the US AQI system, which is widely recognized and employed in many countries due to its clear and consistent method of conveying air quality information, especially regarding health impacts. It’s also more stringent than many other indexes, such as those used in India and China. The US AQI ranges from 0 to 500, with higher values indicating worse air quality. The index is calculated based on the concentrations of several key pollutants, including:
- Particulate Matter (PM2.5 and PM10): Fine particles that can penetrate deep into the lungs and even enter the bloodstream, causing respiratory and cardiovascular problems.
- Ground-level Ozone (O3): A harmful gas formed when pollutants from vehicles and industrial facilities react with sunlight. Ozone can cause respiratory issues and aggravate asthma.
- Carbon Monoxide (CO): A colourless, odourless gas that can be harmful when inhaled in large amounts, leading to headaches, dizziness, and even death at very high levels.
- Sulfur Dioxide (SO2): A gas produced by burning fossil fuels that can cause respiratory problems and contribute to the formation of acid rain.
- Nitrogen Dioxide (NO2): A pollutant primarily emitted from vehicles and industrial activity, contributing to respiratory issues and the formation of smog.
The AQI is divided into six categories, each corresponding to a different level of health concern:
- 0-50 (Good): Air quality is considered satisfactory, and air pollution poses little or no risk.
- 51-100 (Moderate): Air quality is acceptable; however, there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
- 101-150 (Unhealthy for Sensitive Groups): Members of sensitive groups may experience health effects. The general public is not likely to be affected.
- 151-200 (Unhealthy): Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
- 201-300 (Very Unhealthy): Health alert: everyone may experience more serious health effects.
- 301-500 (Hazardous): Health warnings of emergency conditions. The entire population is more likely to be affected.
While many countries, such as India, use their own AQI systems tailored to local environmental conditions and pollutants, Indonesia’s adoption of the US AQI provides consistency with international standards and facilitates easier comparisons with global air quality data.
How to Monitor Air Quality in Indonesia
Given the variability of air pollution across Indonesia, especially during the dry season and haze periods, it’s important to stay informed about local air quality. Fortunately, several tools and apps are available that provide real-time AQI data for different regions across the country.
AirVisual by IQAir:
One of the most popular AQI apps globally, AirVisual provides real-time air quality data for thousands of locations worldwide, including Indonesia. The app uses data from government stations as well as independent monitors, giving users a comprehensive view of air quality. It also provides 7-day forecasts, historical data, and health recommendations based on the current AQI level.
AQICN:
The AQICN website and app are excellent resources for detailed air quality information. They offer real-time data for multiple pollutants, not just the overall AQI. This tool is particularly useful for those who want to delve deeper into the specifics of air pollution, such as tracking individual pollutant levels like PM2.5 or Ozone. Personally, I use this website whenever I want to check historical trends.
BMKG:
The BMKG provides a range of environmental data, including air quality updates, through its website and mobile app. While it is primarily focused on weather and climate, the BMKG’s air quality reports are a reliable source for understanding regional pollution levels.
Jakarta’s Air Quality Monitoring System:
The city government operates an extensive network of air quality monitors for Jakartans and visitors. The data is available through the Jakarta Smart City platform, which can be accessed via its website or app. This tool offers detailed insights into the air quality across different parts of the city.
Regularly checking air quality data is crucial, especially during periods of high pollution or when planning outdoor activities. Many of these apps and tools offer notifications, which can alert you when air quality deteriorates to unhealthy levels. Additionally, it’s advisable to keep track of local news and weather reports, particularly during the dry season, when air quality can change rapidly due to forest fires or industrial emissions.
Staying Safe from Air Pollution in Indonesia
If you must go outside, a respirator is the best way to protect yourself.
Air pollution poses significant health risks when pollution levels can frequently reach hazardous levels. While it’s challenging to avoid exposure completely, you can take several effective measures to protect yourself and minimize the impact of polluted air on your health. From wearing the right type of mask to improving indoor air quality, these strategies can help you stay safe even when air quality deteriorates.
Masking with Respirators
One of the most effective ways to protect yourself from harmful air pollution, particularly in urban areas or during the haze season, is to wear a high-quality respirator. Masks such as N95, KN95, or FFP2 are considered respirators and are designed to filter out fine particulate matter (PM2.5), one of the most dangerous pollutants in the air. These particles are small enough to penetrate the lungs and enter the bloodstream, leading to respiratory and cardiovascular issues. A good respirator mask can significantly reduce your exposure to these harmful particles, especially if you need to spend time outdoors during high-pollution days.
When choosing a respirator, ensure that it fits snugly around your face without any gaps where air can leak in. The respirator’s effectiveness depends on a proper seal, so adjusting the nosepiece and straps to fit securely is crucial. It’s also important to replace the device or its filters regularly, as they can become clogged with particles over time, reducing their effectiveness (or increasing; studies on this show different results). For children particularly vulnerable to air pollution, make sure to use respirators specifically designed for smaller faces to ensure a good fit. Wearing a respirator is a simple yet vital step in protecting your health during periods of high pollution.
Staying Indoors to Avoid the Worst Pollution
During periods of severe air pollution, such as the dry season, when haze and smoke from forest fires are prevalent, staying indoors is one of the most effective ways to minimize exposure to harmful pollutants. Outdoor air can be filled with dangerous levels of particulate matter, ozone, and other pollutants, making it unsafe to spend extended periods outside. Limiting your time outdoors, especially during peak pollution hours, can significantly reduce your exposure to these harmful substances.
When staying indoors, avoiding activities that can further degrade indoor air quality, such as burning candles, smoking, or using certain household cleaners that emit volatile organic compounds (VOCs), is important. Engaging in activities that don’t require heavy physical exertion is also beneficial, as this can increase the amount of polluted air you inhale. If you need to go outside for essential activities, try to schedule them when air quality is better, such as early morning or late evening when traffic emissions are lower. Staying indoors during high pollution periods is crucial in protecting your health and reducing the risks associated with air pollution.
‘Locking Down’ Your House: Air Purifiers and Air Quality Monitors
To further protect yourself and your family from indoor air pollution, it’s essential to ‘lockdown’ your house during periods of severe outdoor pollution. This means keeping all windows and doors closed to prevent polluted air from entering your home. Additionally, using air purifiers with HEPA filters can greatly improve indoor air quality by removing harmful particles such as PM2.5, dust, pollen, and even some viruses and bacteria. Place air purifiers in the rooms where you spend the most time, such as bedrooms and living rooms, to maximize their effectiveness.
Monitoring indoor air quality is equally important. Using an air quality monitor allows you to keep track of the levels of pollutants inside your home so you can take action if they start to rise. Some advanced air purifiers have built-in monitors, but standalone monitors are also available (I’ve also found that the built-in monitors often aren’t particularly accurate). These devices can alert you when pollutant levels are too high, prompting you to increase ventilation, use an air purifier, or take other measures to improve the air quality. Regularly checking and maintaining your air purifiers, such as cleaning or replacing filters, ensures they continue to function effectively. By locking down your house and monitoring indoor air quality, you can create a safer, healthier environment inside your home.
Keeping an Eye on Air Pollution Levels
Regularly monitoring air pollution levels is essential for making informed decisions about your daily activities and minimizing your exposure to harmful pollutants. With the availability of various apps and websites, it’s easier than ever to check the Air Quality Index (AQI) in your area.
